Note: No state administers IQ tests to its residents. These estimates are proxy conversions from standardized achievement scores (NAEP, SAT, ACT) — an approach popularized by McDaniel's 2006 state-IQ estimates in the journal Intelligence — combined with demographic data. Proxy conversions carry real limitations: SAT/ACT participation rates differ sharply by state and bias comparisons, and the variation within any state dwarfs the differences between states. Figures are shown rounded; decimal precision would overstate what these proxies can support. They say nothing about any individual resident.
About Wisconsin's IQ Ranking
Wisconsin ranks in the top 10 thanks to its strong public education tradition, well-regarded university system (UW-Madison is a top research university), and German/Scandinavian cultural heritage that emphasizes education and community investment. The state has traditionally had strong teacher unions and above-average education spending.
What Shapes Wisconsin's Cognitive Profile
Act 10, the 2011 law that curtailed collective bargaining for teachers, triggered waves of retirements and reshaped the teaching profession in Wisconsin more than in any neighboring state, and researchers still debate its effects on instructional quality. Milwaukee operates the nation's oldest urban voucher program, running since 1990, which makes the city a long-term natural experiment in school choice. On NAEP, Wisconsin has repeatedly recorded the largest Black-white achievement gap in the country, concentrated in Milwaukee, even as statewide averages stay above the national mean. Epic Systems in Verona has grown into one of the Midwest's largest software employers, hiring thousands of recent graduates annually and slowing the outflow of UW-Madison talent toward Chicago and the coasts. The Fox Valley's papermaking economy has contracted steadily, pressuring school budgets in former mill towns. Marquette and the Medical College of Wisconsin add private research capacity in Milwaukee. The estimated statewide average masks a Dane County population whose attainment rivals Boston suburbs.
